IMPROVEMENT IN SURGICAL OPERATING-TABLES.

Specification forming part of Letters Patent No. 201.933, dated April 2, 1878; application filed March 31, 1877. v i

To all whom it may concern.-

Be it known thatI, THOMAS MOILROY, of Jersey City, New Jersey, have .invented cer-- tain new and useful Improvements in Operatpurposes of weighing subjects or patients in dead-houses, dissecting-rooms, operatingrooms, or other places.

The invention consists, secondly, in mounting the table-top on a hollow screw, which is used for the purpose of raising and lowering, and serves also for the purpose of a duct or discharge pipe, for carrying off blood and other fluids from the patient or subject on the table, and connects with a sewer or suitable receptacle, a trap being applied beneath the floor to prevent obnoxious gases returning.

The invention consists, thirdly, in constructing a duct or discharge-pipe in telescopic form, to adapt it to accommodate itself to different heights of the table-top.

The invention consists, fourthly, in combinin g with an operating or dissecting table a discharge pipe or duct and a suction apparatus, for the purpose of carrying off unpleasant or deleterious odors.

My invention consists, fifthly, in constructing the table-top of glass or analogous material, and providing it with a neck for attachment to the base, and perforations forming communication between the surface of the table-top and a discharge-pipe beneath.

In the accompanying drawings, Figure 1 is a sectional elevation of one form of my dissecting or operating table, illustrating my invention. Fig. 2 is a side view of a modified form of my device. Fig. 3 is a top View of the same. Fig. 4 is a vertical section of the same on the line 4 4, Fig. 3.

A B represent various parts of the stationary frame. 0 is the platform of a scale, connected by customary hanging-rods D with a beam, E, which is suspended by a hanger, F, from the top B of the frame. In practice,two or more of these weigh-beams are used, affording means for weighing accurately down to quarter-ounces any body up to six hundred glass or other non-conductor of electricity,

provided with 'a neck, N, of the same material or it may be attached to a neck or collar, N of difl erent material, which fits in or on the socket J of the screw H, so as to afford the table-top M a rotation independently of the screw.

The weight of the tabletop and any body 4 thereon is sustained by four or any desirable number of wheels, 0, mounted on the undertable L, and giving freedom of rotation to the table-top. The hollow screw connects, as shown, with apertures or perforations P in the table-top M.

Within the screw descends a pipe, Q, constituting a duct, to discharge from the table, and communicating at the bottom with a sewer or suitable receptacle. The lower part of the pipe Q is adapted to fit telescopically within a stationary pipe, R, communicating with a stench-trap, It, and horizontal pipe S, which is connected with a flue or chimney, T, Fig. 2, ora fan, T, or a steam-blast or other suction apparatus, for the purpose of drawing oif deleterious odors.

The pipe Q, as will be understood from the above explanation, moves up and down with the table M and screw H 5 and in order that it may be always in communication with the horizontal pipe S, it is formed with a vertical slot, g, which is as long as the vertical motion of the table.

The top B of the frame affords a convenient receptacle for instruments of all kinds and other matters. The body of the frame or support A, containing the scale C D E F, may be open, or, if closed, is provided with suitable doors, to afford access to the interior for weigh ing purposes. 7

The lower part of the frame rests on legs a,

as shown, affording room under the horizontal portion of the frame for the feet of the operator.

A vertical rack and pinion, or other suitable elevating device, may be substituted for the screw and nut for elevating the table.

The table may be made round or square, or

of any preferred shape.

A damper 8, may be insertedcinthepipe S, as shown in Fig. 2, for regulating the blast.

The table M is constructed of a non-conducting material, such as glass, so as not to.

. discharge of liquids from-the table.

3. An operating or dissecting table coni structed with atelescopic duct,.for conducting 1 off fluids through suitable discharge-pipes at different heights of the table.

4;. Anoperating or dissecting table connecting,th rou'gh a suitable duct, Wit-11 an. ex-

haust apparatus, for carrying off deleterious odors and gases.

5. An operating or dissecting table with a scale attachment, for Weighing the patient or subject, said" scale admitting a central ventilating and discharge pipe, connecting through a trapwith an outlet for fluid, and above the trap with a ventilating or suction flue.

6. The top M of a surgical operating-table,

constructed of glass, and concave uponits upper surface, as and for the purpose set forth.

7. The top M of a surgical operating-table, constructed of glass, concave on its upper surface, and provided with perforations 1 as and :for the purposeset forth.

8. The table-top M,v constructed of glassor analogous material, and provided with aneck, N, and perforations P, as set forth.
